CAUTION: Safety Instructions
Use the following safety guidelines to help ensure your own personal safety and to help protect
your computer and working environment from potential damage.
General
•
Do not attempt to service the computer yourself unless you are a trained service
technician. Always follow installation instructions closely.
•
To help prevent electric shock, plug the computer and device power cables into properly
grounded electrical outlets. These cables are equipped with 3-prong plugs to help ensure
proper grounding. Do not use adapter plugs or remove the grounding prong from a cable.
If you must use an extension cable, use a 3-wire cable with properly grounded plugs.
•
To help avoid the potential hazard of electric shock, do not use your computer during an
electrical storm.
•
To help avoid the potential hazard of electric shock, do not connect or disconnect any
cables or perform maintenance or reconfiguration of this product during an electrical
storm.
•
If your computer includes a modem, the cable used with the modem should be
manufactured with a minimum wire size of 26 American wire gauge (AWG) and an FCCcompliant RJ-11 modular plug.
•
Before you clean your computer, disconnect the computer from the electrical outlet.
Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol
cleaners, which may contain flammable substances.
•
To help avoid possible damage to the system board, wait 5 seconds after turning off the
computer before disconnecting a device from the computer.

CAUTION: Safety Instructions (continued)
10
•
To avoid shorting out your computer when disconnecting a network cable, first unplug
the cable from the network adapter on the back of your computer, and then from the
network jack. When reconnecting a network cable to your computer, first plug the cable
into the network jack, and then into the network adapter.
•
To help protect your computer from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply
(UPS).
•
Ensure that nothing rests on your computer’s cables and that the cables are not located
where they can be stepped on or tripped over.
•
Do not push any objects into the openings of your computer. Doing so can cause fire or
electric shock by shorting out interior components.
•
Keep your computer away from radiators and heat sources. Also, do not block cooling
vents. Avoid placing loose papers underneath your computer; do not place your computer
in a closed-in wall unit or on a bed, sofa, or rug.
•
Do not spill food or liquids on your computer. If the computer gets wet, consult
"Repairing a Wet Computer."
•
Do not use your computer during an electrical storm unless the AC adapter cable has
been disconnected from the electrical outlet.
•
When you use the AC adapter to run the computer or to charge the battery, place the AC
adapter in a ventilated area, such as a desk top or on the floor.
•
The AC adapter may become hot during normal operation of your computer. Use care
when handling the adapter during or immediately after operation.
When Using Your Computer
As you use your computer, observe the following safe-handling guidelines.
CAUTION: Do not operate your computer with any cover(s) (including computer
covers, bezels, filler brackets, front-panel inserts, and so on) removed.
•
Your computer is equipped with one of the following:
–
A fixed-voltage power supply — Computers with a fixed-voltage power supply do not
have a voltage selection switch on the back panel and operate at only one voltage (see
the regulatory label on the outside of the computer for its operating voltage).
–
An auto-sensing voltage circuit — Computers with an auto-sensing voltage circuit do
not have a voltage selection switch on the back panel and automatically detect the
correct operating voltage.
–
A manual voltage selection switch — Computers with a voltage selection switch on
the back panel must be manually set to operate at the correct operating voltage.
NOTICE: To help avoid damaging a computer with a manual voltage selection switch, set the
switch for the voltage that most closely matches the AC power available in your location. For Japan,
the voltage selection switch must be set to the 115-V position even though the AC power available in
Japan is 100 V. Also, ensure that your monitor and attached devices are electrically rated to
operate with the AC power available in your location.
•
Before working inside the computer, unplug the computer to help prevent electric shock
or system board damage. Certain system board components continue to receive power
any time the computer is connected to AC power.

Dell. Always follow installation and service instructions closely.
NOTICE: To help avoid possible damage to the system board, wait 5 seconds after turning off the
computer before removing a component from the system board or disconnecting a device from the
computer.
1
Perform an orderly computer shutdown using the operating system menu.
2
Turn off your computer and any devices connected to the computer.
3
Ground yourself by touching an unpainted metal surface on the chassis, such as the metal

inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis
to dissipate any static electricity that might harm internal components.
4
Disconnect your computer and devices, including the monitor, from their electrical
outlets. Also, disconnect any telephone or telecommunication lines from the computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:
•
12
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the
cable itself. Some cables have a connector with locking tabs; if you are disconnecting this
type of cable, press in on the locking tabs before disconnecting the cable. As you pull
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also,
before you connect a cable, ensure that both connectors are correctly oriented and
aligned.
When Using Your Computer (continued)
•
Handle components and cards with care. Do not touch the components or contacts on a
card. Hold a card by its edges or by its metal mounting bracket. Hold a component such
as a microprocessor chip by its edges, not by its pins.
CAUTION: There is a danger of a new battery exploding if it is incorrectly installed.
Replace the battery only with the same or equivalent type recommended by the
manufacturer. Do not dispose of the battery along with household waste. Contact
your local waste disposal agency for the address of the nearest battery deposit site.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static
damage, discharge static electricity from your body before you touch any of your computer’s
electronic components, such as the microprocessor. You can do so by touching an unpainted
metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to
remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
•
Do not remove components from their antistatic packing material until you are ready to
install the component in your computer. Just before unwrapping the antistatic packaging,
discharge static electricity from your body.
•
When transporting an electrostatic sensitive component, first place it in an antistatic
container or packaging.
•
Handle all electrostatic sensitive components in a static-safe area. If possible, use
antistatic floor pads and workbench pads.
Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard use may result in injury.
CAUTION: Viewing the monitor screen for extended periods of time may result in
eye strain.
For comfort and efficiency, observe the ergonomic guidelines in "Ergonomic Computing
Habits" when setting up and using your computer.

When Using Your Computer (continued)
Battery Disposal
Your computer uses a lithium battery. The lithium battery is a long-life battery, and it is very
possible that you will never need to replace it. However, should you need to replace it, see
"Replacing the Battery."
Do not dispose of the battery along with household waste. Contact your local waste disposal
agency for the address of the nearest battery deposit site.

Connecting Devices
When you connect external devices to your computer's back panel, follow
these guidelines:
•
Check the documentation that accompanied the device for specific
installation and configuration instructions.
For example, you must connect most devices to a particular
input/output (I/O) connector to operate properly. Also, external
devices like a mouse or printer usually require you to load device
drivers into computer memory before they will work.
•
Always attach external devices while your computer is turned off. Then
turn on the computer before turning on any external devices, unless
the documentation for the device specifies otherwise. (If the computer
does not seem to recognize the device, try turning on the device before
turning on the computer.)
A bout Yo ur Computer
29
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m
NOTICE: When you disconnect external devices from the back of the
computer, wait 10 to 20 seconds after turning off the computer before you
disconnect any devices to avoid possible damage to the system board.
Parallel Connector
This is used to connect printers. Default designation is LPT1.
NOTE: The integrated
parallel connector is
automatically disabled if
the computer detects an
installed expansion card
containing a parallel
connector configured to
the same address as
specified in “Additional
System Setup Options.”
NOTE: USB mice only
wakes the computer from
the S1 (standby) and S3
(suspend to RAM) states
with a click.
Mouse Connector
Turn off the computer and any attached devices before connecting a mouse
to the computer. If your computer uses Microsoft Windows 2000 or
Windows NT 4.0, Dell installed the necessary mouse drivers on your hard
drive.
USB Connectors
These are used to attach USB-compliant devices such as keyboards, mice,
printers, and computer speakers to your computer.
Integrated Network Adapter Connector
The network adapter, which includes a Remote Wake Up feature, has the
following lights:
•
A yellow network activity light flashes when the computer is
transmitting or receiving network data. (A high volume of network
traffic may make this light appear to be in a steady “on” state.)
•
A dual-colored link integrity light, which is green when a good
connection exists between a 10-megabit per second (Mbps) network
and the computer, or is orange when a good connection exists between
a 100-Mbps network and the computer. When the light is off, the
computer is not detecting a physical connection to the network.
Network Cable Requirements
The network adapter connector attaches an unshielded twisted pair (UTP)
Ethernet cable to your computer. Press one end of the UTP cable to an RJ45
jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending
on your network configuration, and press the other end of the UTP cable
into the network adapter connector until the cable snaps securely into place.
Dell recommends the use of Category 5 wiring and connectors for our
customers’ networks.

reassign the serial connector’s designation if you add an expansion card
containing a serial connector using this designation.
If you set the computer’s serial connectors to Auto in system setup and add
an expansion card containing a serial connector configured to a specific
designation, the computer automatically maps (assigns) the integrated
ports to the appropriate COM setting as necessary.
Before you add a card with a serial connector, check the documentation that
accompanied your software to make sure that the software can be mapped
to the new COM port designation.
Keyboard Connector
Attach the keyboard cable to the 6-pin connector on the back panel.

Password Protection
The computer provides two types of password protection:
•
System Password
•
Setup Password
NOTE: Before you
purchase an antitheft
device, make sure it
works with the security
cable slot on your
computer.
System Password
System passwords allow only those who know the password to have full use
of the computer. Your Dell computer does not have the system password
feature enabled when you receive it.
NOTICE: Although passwords provide security for the data on your computer,
they are not foolproof. If your data requires more security, it is your
responsibility to obtain and use additional forms of protection, such as data
encryption programs.
NOTICE: If you leave your computer running and unattended without having
a system password assigned, or if you leave your computer unlocked so that
someone can disable the password by changing a jumper setting, anyone can
access the data stored on your hard drive.
System Password settings in system setup:
•
Enabled — a system password is assigned
•
Disabled — system password feature is disabled by a jumper setting on
the system board
•

Software Installation and
Configuration
When you obtain software, check it for viruses with virus-scanning software
before installing it on your computer's hard drive. Viruses can quickly use all
available computer memory, damage or destroy data stored on the hard
drive, and permanently affect the performance of the programs they infect.
Several commercial virus-scanning programs are available for purchase, and
most bulletin board services (BBSs) on the Internet archive freely
distributed virus-scanning programs that you can download with a modem.
Before you install a program, read its documentation to learn how the
program works, what hardware it requires, and what its defaults are. A
program usually includes installation instructions in its accompanying
documentation and a software installation routine on its program floppy
disks or CD(s).
The software installation routine assists you in transferring the appropriate

TAPI
The telephony applications programming interface (TAPI) system-board
connector uses a 4-pin cable to interface your internal TAPI-compliant
expansion card with the audio system in your computer. To locate the TAPI
system-board connector, see “System Board Components.” Your computer
supports TAPI-compliant cards using the standard TAPI connector (labeled
TELE). For example, you can connect your modem to the TAPI connector
and then use your audio speakers and microphone as a speakerphone. The
microphone carries your voice into the computer and then through the
TAPI system board connector to your modem card. The caller’s voice enters
through the modem card to the TAPI system board connector and then out
to the speakers. You can also use this configuration to record and play sound
files over the phone.
NOTE: See the
documentation that came
with the TAPI-compliant
expansion card for more
information on using
TAPI devices and to
verify the card works with
your computer.

Memory
You can increase memory up to 1 gigabyte (GB) by using synchronous
dynamic random-access memory (SDRAM) dual in-line memory modules
(DIMMs). The system board illustration shows the location of the DIMM
sockets on the system board. (DIMMs may either be error checking and
correction [ECC] or non-error checking and correction [non-ECC].
However, all DIMMs must be the same type of memory—either ECC or
non-ECC.)
When you add memory, you may install DIMMs in either socket. For
optimum operation, Dell recommends that you install a DIMM in socket A
first (closest to the processor) before installing a DIMM in socket B.
Installing DIMMs
CAUTION: To avoid the possibility of electric shock, turn off the
computer and any devices, disconnect them from their electrical
outlets, and then wait 10 to 20 seconds before you open the

IDE Drive Addressing
All IDE devices require that you configure the cable select setting, which
assigns master and slave status to devices according to their position on the
interface cable. You usually configure a drive for cable select by setting a
jumper or switch, depending on the drive. Refer to the drive documentation
in your upgrade kit for information on configuring devices for the cable
select setting. When you connect two IDE devices to a single IDE interface
cable and configure them for the cable select setting, the device attached to
the last connector on the interface cable is the master or boot device (drive
0), and the device attached to the middle connector on the interface cable
is the slave device (drive 1).
108
Installing Upgrades
With the two IDE interface connectors on the system board, your computer
supports up to two IDE devices. IDE hard drives should be connected to
the IDE interface connector labeled “IDE1.” (Always connect CD/DVD
drives to the IDE interface connector labeled “IDE2.”)
Connecting Drives
When you install a drive, you connect two cables—a DC power cable and
an interface cable—to the back of the drive. Your drive’s power input
connector (to which you connect the DC power cable) resembles the
following connector.
Power Cable Connector

When you attach the interface cable to a drive, be sure to match the colored
stripe on the cable to pin 1 of the drive’s interface connector. For the
location of pin 1 on the drive’s interface connector, see the documentation
that came with the drive.
When you disconnect an interface cable from the system board, be sure to
press in on the locking tabs on the cable connector before you disconnect
the cable. When you attach an interface cable to the system board, be sure
that the locking tabs snap into place so that the cable is firmly attached to
the connector on the system board.
Most interface connectors are keyed for correct insertion; that is, a notch or
a missing pin on one connector matches a tab or a filled-in hole on the other
connector. Keyed connectors ensure that the pin-1 wire in the cable
(indicated by the colored stripe along one edge of the cable) goes to the
pin-1 end of the connector. The pin-1 end of a connector on a board or a
card is usually indicated by a silk-screened “1” printed directly on the board
or card.
110
Installing Upgrades
NOTICE: When you connect an interface cable, do not reverse the interface
cable (do not place the colored stripe away from pin 1 of the connector).
Reversing the cable prevents the drive from operating and could damage the
controller, the drive, or both.
Hard Drives
CAUTION: To avoid the possibility of electric shock, turn off the
computer and any devices, disconnect them from electrical
outlets, and then wait 10 to 20 seconds before you open the
computer cover. Also, before you install a drive, see the other
precautions in “CAUTION: Safety Instructions.”
1
If you are replacing a hard drive that contains data you want to keep,
back up your files before you begin this procedure.
2
If you are adding an additional hard drive to a small mini-tower
computer, see “Adding a Second Hard Drive — Small Mini-Tower
Computer.”
NOTICE: Ground yourself by touching an unpainted metal surface on the
back of the computer.
NOTICE: To avoid damage to the drive, do not set it on a hard surface.
Instead, set the drive on a surface, such as a foam pad, that sufficiently
cushions it.
3
Open the computer cover.

On the small desktop computer, the hard drive may or may not have a
plastic shroud cover. (Operating the computer without a hard-drive
shroud does not affect its performance.) If your computer's hard drive
does not have a shroud, proceed to the next step. If your computer's
hard drive does have a shroud, remove it by pressing in on the indented
tab at the top of the shroud and lifting the shroud away.

Battery
A 3.0-V CR2032 lithium coin-cell battery installed on the system board
maintains system configuration, date, and time information in a special
section of memory.
The operating life of the battery can extend up to 10 years. The battery may
need replacing if an incorrect time or date is displayed during the boot
routine along with a message such as:
Time-of-day not set - please run SETUP program
or
Invalid configuration information please run SETUP program
or
Strike the F1 key to continue,
F2 to run the setup utility
To determine whether you need to replace the battery, reenter the time and
date through system setup and exit the program properly to save the
information. Turn off your computer and disconnect it from the electrical
outlet for a few hours, and then reconnect the computer, turn it on, and
enter system setup. If the date and time are not correct in system setup,
replace your battery.
You can operate your computer without a battery; however, without a
battery, the configuration information is erased if the computer is turned off
or unplugged from the electrical outlet. In this case, you must enter system
setup and reset the configuration options.

Computer Beep Codes
When errors occur during a boot routine that cannot be reported on the
monitor, your computer may emit a series of beeps that identify the
problem. The beep code is a pattern of sounds: for example, one beep,
followed by a second beep, and then a burst of three beeps (code 1-1-3)
means that the computer was unable to read the data in nonvolatile
random-access memory (NVRAM). This information is invaluable to the
Dell support staff if you need to call for technical assistance.
When a beep code is emitted, write it down on a copy of the Diagnostics
Checklist found in “Getting Help,” and then look it up in “Computer Beep
Codes.” If you are unable to resolve the problem by looking up the meaning
of the beep code, use the Dell Diagnostics to identify a more serious cause.
If you are still unable to resolve the problem, see “Getting Help” for

Warning Messages
A warning message alerts you to a possible problem and asks you to do
something before execution continues. For example, before you format a
floppy, a message may warn you that you may lose all data on the floppy as a
way to protect against inadvertently erasing or writing over the data. These
warning messages usually interrupt the procedure and require you to
respond by typing y (yes) or n (no).

Back Panel Lights
When you turn on your computer, it performs a power-on self-test (POST),
which is a series of self-diagnostic checks. A successful POST ends with a
single beep that signifies the start of normal operation. If the computer fails
to emit the single beep or appears to stop responding during POST, a series
of lights located at the rear of the computer can help you understand which
POST test failed or why the computer stopped responding. These lights
indicate problems encountered during POST only, not during normal
operation.
CAUTION: Before servicing any components inside your computer,
see “CAUTION: Safety Instructions.”
The light patterns described in the following table can help you determine
what to do to resolve the problem. If a problem resolution requires you to
open the computer chassis, see “Finding Solutions” for procedures you need
to complete prior to performing the suggested resolution. If the problem
persists after you perform the suggested problem resolution(s), contact Dell
for further help.

Software Problems
This section provides general guidelines for analyzing software problems.
For detailed troubleshooting information on a particular program, see the
documentation that accompanied the software or consult the support
service for the software.
If your computer is behaving erratically, back up your files immediately. If
your computer has a tape drive installed, see the documentation that came
with the tape backup software for instructions on performing a backup
operation. Otherwise, see your operating system documentation for
information on backing up data files.
206
Solving Pr oblems
Basic Checks:
•
Ensure that the application program is compatible with the operating
system installed in your computer and that your computer meets the
minimum hardware requirements needed to run the software.
•
Ensure that you properly installed and configured the application
program. Reinstall the program if necessary.
•
Consult the software documentation or contact the software
manufacturer for detailed troubleshooting information on a particular
application program.
•
Ensure that you have not made an error while entering data.
•
Make sure that problems are not caused by a virus — Use a virusscanning application program to check the floppy disks or CDs.
•
Verify that the program’s device drivers do not conflict with certain
application programs.
•
Confirm that a problem is software-related by running the System
Board Devices tests in the Dell Diagnostics. If all tests run
successfully, the error condition may be related to a software problem.
•
Ensure that the use of terminate-and-stay-resident (TSR) programs
has not resulted in a memory conflict.
•
Remove or confirm the possibility of a program conflict by rebooting
your computer.
•
Make sure that a hardware conflict does not exist between devices.
Operating System Compatibility
Make sure the computer's operating environment is set up to accommodate
the application programs you use. Whenever you change the operating
environment parameters, you may also affect the successful operation of the
application programs. Sometimes, after modifying the operating
environment, you may need to reinstall a program that no longer runs
properly.

Input Errors
If a specific key or set of keys is pressed at the wrong time, a program may
give you unexpected results. See the documentation that came with your
application program to make sure the values or characters you are entering
are valid.
Error Messages
Error messages can be produced by an application program, the operating
system, or the computer. “Messages and Codes” discusses the error
messages that are generated by the computer. If you receive an error
message that is not listed in “Messages and Codes,” check your operating
system or application program documentation.
Device Drivers
Programs that use specialized subroutines called device drivers can also
cause problems with your computer. For example, a variation in the way the
data is sent to the monitor may require a special screen driver program that
expects a certain kind of video mode or monitor. In such cases, you may
have to develop an alternative method of running that particular program—
the creation of a boot file made especially for that program, for example.
Call the support service for the software you are using to help you with this
problem.
Memory-Resident Programs
Many utilities and supplementary programs load either when the computer
boots or from an operating system prompt. These programs are designed to
stay resident in computer memory and thus always be available for use.
Because they remain in the computer's memory, memory conflicts and
errors can result when other programs require use of all or part of the
memory already occupied by these TSR programs.
208
Solving Pr oblems
Typically, your operating system's start-up files (such as config.sys and
autoexec.bat) contain commands to start TSR programs when you boot
your computer. If you suspect that one of these TSR programs is causing a
memory conflict, remove the commands that start them from the start-up
files. If the problem you were experiencing does not recur, one of the TSR
programs probably created the conflict. Add the TSR commands back into
the start-up files one at a time until you identify which TSR program is
creating the conflict.
Program Conflicts
Some programs may leave portions of their setup information behind, even
though you have exited from them. As a result, other programs cannot run.
Rebooting your computer can confirm whether or not these programs are
the cause of the problem.
Memory Address Conflicts
Memory address conflicts occur when two or more devices try to access the
same address in the upper memory blocks (UMB). For example, if a network
expansion card and an expanded-memory page frame are assigned an
overlapping block of addresses, a memory address conflict arises. As a result,
when you try to log in to the network, the operation fails.
To resolve this type of conflict, you can change the address of one of the
devices. For example, in the case of the network expansion card and
expanded-memory page frame address conflict, you can move the network
card to an address block in the range of CC000h through D0000h. To
reassign the expansion card's address block, see the documentation for the
card.
Interrupt Assignment Conflicts
Problems can arise if two devices attempt to use the same interrupt request
(IRQ) line. To avoid this type of conflict, check the documentation for the
default IRQ-line setting for each installed expansion card, then consult the
following table to configure the card for one of the available IRQ lines.

telephone at or near the computer. You may be asked to type some
commands at the keyboard, relay detailed information during operations, or
try other troubleshooting steps possible only at the computer itself. Ensure
that the computer documentation is available.
CAUTION: Before working inside your computer, read the safety
instructions.

Regulatory Notices
Electromagnetic Interference (EMI) is any signal or emission, radiated in
free space or conducted along power or signal leads, that endangers the
functioning of a radio navigation or other safety service or seriously
degrades, obstructs, or repeatedly interrupts a licensed radio
communications service. Radio communications services include but are
not limited to AM/FM commercial broadcast, television, cellular services,
radar, air-traffic control, pager, and Personal Communication Services
(PCS). These licensed services, along with unintentional radiators such as
digital devices, including computer systems, contribute to the
electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic
equipment to function properly together in the electronic environment.
While this computer system has been designed and determined to be
compliant with regulatory agency limits for EMI, there is no guarantee that
interference will not occur in a particular installation. If this equipment
does cause interference with radio communications services, which can be
determined by turning the equipment off and on, you are encouraged to try
to correct the interference by one or more of the following measures:
•
Reorient the receiving antenna.
•
Relocate the computer with respect to the receiver.
•
Move the computer away from the receiver.
•
Plug the computer into a different outlet so that the computer and the
receiver are on different branch circuits.
If necessary, consult a Dell Technical Support representative or an
experienced radio/television technician for additional suggestions.
Dell computer systems are designed, tested, and classified for their
intended electromagnetic environment. These electromagnetic
environment classifications generally refer to the following harmonized
definitions:
236
A d d i t i o n a l I n f o r ma t i o n
•
Class A is typically for business or industrial environments.
•
Class B is typically for residential environments.
Information Technology Equipment (ITE), including peripherals,
expansion cards, printers, input/output (I/O) devices, monitors, and so on,
that are integrated into or connected to the system should match the
electromagnetic environment classification of the computer system.
A Notice About Shielded Signal Cables: Use only shielded cables for
connecting peripherals to any Dell device to reduce the possibility of
interference with radio communications services. Using shielded cables
ensures that you maintain the appropriate EMC classification for the
intended environment. For parallel printers, a cable is available from Dell.
If you prefer, you can order a cable from Dell on the World Wide Web at
accessories.us.dell.com/sna/category.asp?category_id=4117.
Most Dell computer systems are classified for Class B environments.
However, the inclusion of certain options can change the rating of some
configurations to Class A. To determine the electromagnetic classification
for your system or device, refer to the following sections specific for each
regulatory agency. Each section provides country-specific EMC/EMI or
product safety information.
FCC Notices (U.S. Only)
Most Dell computer systems are classified by the Federal Communications
Commission (FCC) as Class B digital devices. To determine which
classification applies to your computer system, examine all FCC
registration labels located on the bottom, side, or back panel of your
computer, on card-mounting brackets, and on the cards themselves. If any
one of the labels carries a Class A rating, your entire system is considered to
be a Class A digital device. If all labels carry an FCC Class B rating as
distinguished by either an FCC ID number or the FCC logo, ( ), your
system is considered to be a Class B digital device.
Once you have determined your system’s FCC classification, read the
appropriate FCC notice. Note that FCC regulations provide that changes
or modifications not expressly approved by Dell could void your authority to
operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions:
•
This device may not cause harmful interference.
A dditional I nfor mation
237
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m
•
This device must accept any interference received, including
interference that may cause undesired operation.
Class A
This equipment has been tested and found to comply with the limits for a
Class A digital device pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the manufacturer’s instruction
manual, may cause harmful interference with radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference, in which case you will be required to correct the interference at
your own expense.
Class B
This equipment has been tested and found to comply with the limits for a
Class B digital device pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the
manufacturer’s instruction manual, may cause interference with radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, you are encouraged to try to correct the
interference by one or more of the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and the receiver.
•
Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
•
Consult the dealer or an experienced radio/television technician for
help.

ENERGY STAR® Emblem
The EPA's ENERGY STAR® Computers program is a joint effort between
the EPA and computer manufacturers to reduce air pollution by promoting
energy-efficient computer products. The EPA estimates that use of
ENERGY STAR® computer products can save computer users up to two
billion dollars annually in electricity costs. In turn, this reduction in
electricity usage can reduce emissions of carbon dioxide, the gas primarily
responsible for the greenhouse effect, and sulfur dioxide and nitrogen
oxides, the primary causes of acid rain.
You can also help reduce electricity usage and its side effects by turning off
your computer when it is not in use for extended periods of time,
particularly at night and on weekends.

Ergonomic Computing Habits
CAUTION: Improper or prolonged keyboard use may result in
injury.
CAUTION: Viewing the monitor screen for extended periods of
time may result in eye strain.
For comfort and efficiency, observe the following ergonomic guidelines
when setting up and using your computer:
•
Position your computer so that the monitor and keyboard are directly
in front of you as you work. Special shelves are available (from Dell and
other sources) to help you correctly position your keyboard.
•
Set the monitor at a comfortable viewing distance (usually 510 to 610
millimeters [20 to 24 inches] from your eyes).
•
Make sure the monitor screen is at eye level or slightly lower when you
are sitting in front of the monitor.
•
Adjust the tilt of the monitor, its contrast and brightness settings, and
the lighting around you (such as overhead lights, desk lamps, and the
curtains or blinds on nearby windows) to minimize reflections and
glare on the monitor screen.
•
Use a chair that provides good lower back support.
•
Keep your forearms horizontal with your wrists in a neutral,
comfortable position while using the keyboard or mouse.
•
Always leave space to rest your hands while using the keyboard or
mouse.
•
Let your upper arms hang naturally at your sides.
•
Sit erect, with your feet resting on the floor and your thighs level.
•
When sitting, make sure the weight of your legs is on your feet and not
on the front of your chair seat. Adjust your chair’s height or use a
footrest, if necessary, to maintain proper posture.
•
Vary your work activities. Try to organize your work so that you do not
have to type for extended periods of time. When you stop typing, try
to do things that use both hands.

Help and Support Center
The Help and Support Center, introduced with Microsoft Windows
Millennium Edition (Me), replaces Windows Help from earlier operating
systems. The Help and Support Center provides an integrated resource
center for information and assistance in using, configuring, and
troubleshooting your computer and installed hardware devices and software.
For Windows XP, the Help and Support Center features expanded search
capabilities, including full-text search and the capability to search across
multiple remote sites in addition to files resident on the hard drive. You can
use a single print command to print an entire chapter of help content.

To open Help and Support Center, click the Start button, and then click
Help and Support. From the home page, you can conduct a search or select
categories of information, leading to task and information topics covering
the use of your computer. Click User and System Guides for information on
using your Dell™ computer, including installed hardware devices and
software.
New User Interface
Windows XP features a redesigned user interface with a new visual style, a
less cluttered desktop, and built-in desktop cleanup features. Window
layout has also been changed for Windows XP and, as in the Control Panel,
emphasizes task presentation. The Start menu has been redesigned. The
left half of the new Start menu includes the most frequently used icons. As
you use your computer, the icons in this area are changed and rearranged
depending on your computer usage patterns. If you wish to keep one of the
icons permanently in its location, right-click the icon and click Pin to Start
menu.
To access all the programs installed on the computer, click All Programs at
the bottom of the Start menu. The right half of the new Start menu
contains useful icons for accessing your files, configuring the computer, and
finding information and assistance. The Dell Solution Center icon opens a
portal to services and application programs installed on your Dell computer.
Switching to Classic View
If you wish, you may change the appearance of the Start menu, desktop and
windows, or Control Panel layout to that of earlier Windows operating
systems. These classic view options are independent of each other.
You can easily switch back and forth between the new Control Panel
category view and the classic icon view by clicking Switch to Classic View or
Switch to Category View in the upper left area of the Control Panel
window. This can be handy if you would like to take advantage of the new,
task-oriented features of the Windows XP Control Panel, but you are
accustomed to performing a particular task with the icon-oriented classic
Control Panel.
To change the appearance of the Start menu to the classic view:

Clean Desktop Wizard
Another feature of Windows XP is the Desktop Cleanup Wizard. The
wizard runs 7 days after you first start your computer and every 60 days after
that. The Desktop Cleanup Wizard first opens a dialog box informing you
that there are unused icons on the desktop and asking whether you want to
run the wizard. If you elect to run the wizard, it places unused desktop icons
in the folder C:\Desktop Icons.
The default for the Desktop Cleanup Wizard is on. To turn the wizard off:
1
Right-click anywhere on the main desktop screen and click Properties.
2
Select the Desktop tab and click Customize Desktop.

Click Finish to remove the shortcuts and close the wizard.
The shortcuts are moved to the folder C:\Desktop Icons.
To access desktop icons removed by Windows XP, click the Start button,
and then click Dell Solution Center.
Taskbar Grouping
The Windows taskbar is a row of buttons that typically displays across the
bottom of the screen. The taskbar includes the Start menu button and a
button for each open application. (The taskbar also includes the Quick
Launch icons and the notification area.) Windows XP groups multiple
instances of the same application on the taskbar. For example, if six
instances of Internet Explorer are open, each displaying a button on the
taskbar, Windows XP groups the buttons next to one another on the taskbar.
If space becomes an issue on the taskbar, Windows XP consolidates all the
Internet Explorer buttons into a single button. When clicked, that button
expands to a menu of the six Internet Explorer active sessions.
Notification Area Cleanup
Over time, software icons tend to proliferate in the notification area, the
area in the bottom right corner of the Windows desktop. Windows XP
detects when icons in the notification area are not being accessed and hides
them. A caret, or chevron, button indicates that there are hidden icons that
can be viewed by selecting the button. You can also configure the
notification area manually by right-clicking the taskbar, selecting Properties,
and then clicking Customize... in the Taskbar and Start Menu Properties
window. For example, you may choose to hide the antivirus program icon
because it is rarely accessed, but display the audio volume icon because it is
used frequently. The notification area cleanup feature is automatically
enabled when the operating system is installed, but you may disable it by
unchecking Hide inactive icons in the Taskbar and Start Menu Properties
window.

Files and Settings Transfer Wizard
The Files and Settings Transfer Wizard is used to migrate personal files and
settings from one computer to another (for instance, when upgrading to a
new computer). Personal files include the documents, images, spreadsheets,
presentations, and e-mail messages on your computer. User settings include
display properties, window sizes, toolbar settings, dial-up connections,
Internet bookmarks, and so forth on your computer. The Files and Settings
Transfer Wizard is run on a source (old) computer to collect the data and is
run again on the destination (new) computer to import the data. If the old
computer is using an earlier operating system, the wizard can be launched
either from the Windows XP CD or from a diskette created on the new
Windows XP computer. You transfer the data to the new computer over a
network or direct serial connection, or store it on a removable medium such
as a floppy disk, Zip disk, or writable CD.
To use the Files and Settings Transfer Wizard:
1
On the new Windows XP computer, click the Start button, point to
All Programs—> Accessories—> System Tools, and click Files and
Settings Transfer Wizard.
2
On the Files and Settings Transfer Wizard welcome screen, click
Next>.
3
On the Which computer is this? screen, select New Computer, and
then click Next>.
The Do you have a Windows XP CD? screen appears.
The Files and Settings Transfer Wizard guides you through the steps
necessary to transfer user settings, personal files, or both to the new
computer. If a CD drive is not available, the wizard allows you to create a
wizard diskette to run on your old computer.
NOTE: The time required to collect and transfer data depends on the amount
of data collected. Times can vary from just a few minutes to several hours.

Application and Device Compatibility
Although Windows XP is designed to be compatible with a wide range of
application programs and hardware devices, some older programs and
devices may not be usable. Check the Microsoft Web site at
www.microsoft.com for application programs and hardware devices known
to be compatible. When buying new software and devices, look for those
that are labeled as ready for Windows XP. If you encounter problems using
an application program designed for an earlier Windows operating system,
Windows XP provides a compatibility mode feature (see “Program
Compatibility Wizard”). If you are unsuccessful at installing application
programs or hardware devices designed to operate on earlier Windows
operating systems, contact the manufacturer of the product for information
or updates for Windows XP.
Windows XP also includes a new technology that addresses the problems
sometimes encountered on previous operating systems with Windows
application programs that, when installed, replace current versions of
certain Windows files with older versions. This situation can cause
problems with the newer application programs, which rely on the replaced
files. To eliminate this problem and improve operating system stability,
Windows XP manages multiple versions of files and invokes the correct
version required by a program.
NOTE: If you experience problems with your operating system or other
applications after performing an installation, you can use System Restore to
return your computer to a previous stable condition.
Program Compatibility Wizard
A program compatibility feature is provided in Windows XP that solves
some issues that may be encountered when attempting to run older
application programs. Using the Program Compatibility Wizard, you can
configure a program to run in an environment closer to Windows 95,
Windows 98/Me, Windows NT 4.0 with Service Pack 5, or Windows 2000.
To use the Program Compatibility Wizard:
1
Click the Start button, point to All Programs—> Accessories, and
click Program Compatibility Wizard.

Click Finish to close the wizard.
System Restore
The System Restore feature of Windows XP provides the capability to
restore the operating system, in the event of a problem, to a previous state
without losing personal data files (such as Word documents, drawings, or email).
System Restore actively monitors system file changes and some application
file changes to record or store previous versions before the changes occurred.
System Restore maintains a rolling record of restore points; to limit the
amount of space used, older restore points are purged to make room for
newer ones.
In the event of a serious operating system problem, System Restore can be
used from Safe Mode or Normal Mode to go back to a previous system state,
restoring optimal system functionality.
NOTE: System Restore does not revert user data or document files, so
restoring does not cause loss of work, mail, or browsing history and favorites.
10
M i c r o s o f t ® W i n d o w s ® X P Fe a t u r e s
NOTE: Dell recommends that you make regular backups of your data files.
System Restore does not monitor changes to or recover your data files. In the
event the original data on the hard drive is accidentally erased or overwritten
or becomes inaccessible because of a hard-drive malfunction, backup files are
required to recover lost or damaged data.
Using System Restore
System Restore monitors a core set of system and application program files,
recording and sometimes copying states of these files before changes are
made. System Restore automatically creates restore points; no user
intervention is required. In addition, you can create restore points manually,
if desired.
Restore points are created to allow you to choose previous system states.
Each restore point gathers the necessary information needed to restore to a
precisely chosen system state. There are three types of restore points:
•
System (automatically created) restore points (scheduled by your
computer)
•
Installation (event-triggered) restore points (when a program is
installed)
•
Manual restore points (created by you as needed)
Scheduled Automatic Restore Points
By default, System Restore creates a restore point every day that the
computer is running. If your computer is off for more than a day, a new
restore point is created the next time you turn the computer on.
Event-Triggered Restore Points
Event-triggered restore points are created before key changes are made to
the system. System Restore automatically creates a restore point before the
following events:
•
Application installations — System Restore creates a restore point
before you install an application program designed for Windows XP.
You may wish to create a manual restore point before attempting to
install an older program.
Micr os of t® Wi ndows® XP Featur es
11
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m
•
AutoUpdate installation — When you choose to install the update,
System Restore creates a restore point before the actual installation of
the update begins.
•
Restore operation — The restore operation itself also creates a restore
point for undo purposes.
•
Microsoft Backup Utility recovery — Before Microsoft Backup Utility
(only available in Windows XP Professional) performs a backup
recovery, System Restore creates a restore point.
•
Unsigned driver installation — The INF installer of Windows detects
unsigned device-driver installations. Drivers that are signed
(electronically certified by the device manufacturer) do not generate a
restore point.
Manual Restore Points
If you are logged on to the computer as computer administrator or as a user
with administrator rights, you may create and name an on-demand restore
point. (For information on types of user accounts, see “How to Add Users.”)
This is useful to create a checkpoint to return to before making a
particularly risky change, before leaving a shared system to other users, or at
a particular state you believe is optimal.
To create a restore point, perform the following steps:
1
Click the Start button, point to All Programs—> Accessories—>
System Tools, and then click System Restore.
2
Select Create a restore point and click Next>.
3
Type a description of the restore point and click Create.
The date and time are automatically added to the description of the
new restore point.
Restore Process
As the computer is used over time, restore points are collected in the archive
without any management or intervention. If you encounter operating
system problems, you can use the System Restore feature to select any of
the restore points presented through the System Restore Wizard.
If problems occur after installing a device driver, you should first attempt to
use Driver Rollback. If that is unsuccessful, then use System Restore.

previously installed version. When you install a new device driver that
causes system instability, use Driver Rollback to reinstall the previous
drivers. In the event that Driver Rollback cannot reinstall your previous
driver, you can use System Restore to return your operating system to its
state before the new device driver installation.

User Accounts and Fast User Switching
NOTE: Fast User Switching is the default user screen for both Home and
Professional editions, but is disabled in Windows XP Professional when the
computer is a member of a computer domain.
Microsoft Windows XP includes a new feature that provides multiuser
access to a single computer. Fast User Switching, which is available in both
the Home and Professional editions, allows users to access the computer
with their specific settings, including the desktop and various applications,
without requiring the previous user to log off. New users log on and switch
from the original user’s session to their own. New users can run their
desktop and applications without interfering with the original user. When
the original user returns, that user can switch back to the desktop and
applications with the original settings. All of this is accomplished without
the delay of each individual user logging off the computer.
During setup, the computer administrator creates all the accounts that will
be used on the computer. (For information on types of accounts and adding
new accounts, see “How to Add Users.”) When the computer starts, the
main user Welcome screen appears with all of the user names. From this
screen you select an account and log in to that session.
How to Use Fast User Switching
To access Fast User Switching, perform the following steps:
14
1
Click the Start button and click Log Off.
2
When the Log Off Windows screen appears, click either Switch User
or Log Off.
M i c r o s o f t ® W i n d o w s ® X P Fe a t u r e s
When you select Switch User, the main user Welcome screen appears. You
can then select your account name and log in. Your personal desktop
appears.
What Happens When a Fast User Switch Occurs?
When a fast user switch occurs, the original user is not logged off the
computer as previously happened on other Microsoft operating systems. On
Windows XP, the user's logon remains active, but is replaced by the new
user. Users can switch between login IDs as often as they want.
However, user applications active during a user switch remain active and
running in the background while the new user is working; this can result in a
slower computer until the process finishes. For example, if one user is
downloading a large file from the Internet and another user logs on to the
computer, the file download continues in the background until it is
complete.
While most applications continue to run in the background during a fast
user switch, multimedia applications do not. Because multimedia
applications use resources that cannot easily be shared between different
users on a single computer, those applications terminate during the user
switch, allowing the new user to take full advantage of the multimedia
capabilities.
Special Considerations With Fast User Switching
Considerations when using Fast User Switching include:
•
Some older Windows games may not operate with a fast user switch.
•
Multimedia games may shut down on a fast user switch.
•
DVD software shuts down and requires a restart when the user comes
back.
•
Computers with low memory configurations can experience problems.
The computer uses memory to keep the first user's programs running
in the background while the second user is logged on. On computers
with limited memory, this can cause the entire computer to run slowly.
Fast User Switching is off by default on computers with less than
128 megabytes (MB) of random-access memory (RAM).
Micr os of t® Wi ndows® XP Featur es
15
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m
Fast User Switching is unavailable if the computer has Windows XP
Professional installed and is a member of a computer domain.
How to Turn Off Fast User Switching
You must have a computer administrator account on the computer to turn
off Fast User Switching. (For information on types of accounts, see “How to
Add Users.”)
To disable Fast User Switching, perform the following steps:
1
Click the Start button, and click Control Panel.
2
In the Control Panel window, click User Accounts.

Under Pick a task, click Change the way users log on or off and do one
of the following:
4
•
Select the Use Fast User Switching to log off check box to enable
Fast User Switching.
•
Deselect the Use Fast User Switching to log off check box to
disable Fast User Switching.
Click Apply Options.
How to Add Users
Only a computer administrator or a user with administrator rights can
create multiple user accounts. The individual who performs the initial
operating system setup creates a computer administrator account and can
add any number of users during the initial setup. All user accounts created
during setup have administrator rights.
After initial operating system setup, the computer administrator or a user
with administrator rights can create additional user accounts.

Home and Small Office Networking
The Network Setup Wizard includes a checklist and steps to guide you
through the process of sharing resources, such as files, printers, or an
Internet connection, between computers in a home or small office. In
Windows XP, Microsoft has improved the online documentation and
usability of operating-system tools for setting up a home or small office
network. New features in the operating system include support for the
Point-to-Point Protocol over Ethernet (PPPoE) and a built-in firewall.
Network Setup Wizard
The Home Network Wizard first appeared in Windows Me. To make setting
up a home or small office network easier, Microsoft developed an enhanced
Network Setup Wizard for Windows XP. This version provides more
complete online documentation and support for setting up a home or small
office network. The new wizard automatically enables the personal firewall
discussed later in this section (see “Internet Connection Firewall”).

Internet Connection Firewall
Today's always-on cable modem and DSL Internet access connections offer
unprecedented bandwidth to the home, but also leave the connected
computer or home network vulnerable to hacker attacks. The nature of
these attacks varies, but the goal is to gain access to individual computers
attached to the Internet. With this access, a hacker can browse the hard
drive and add or delete files, discover passwords and credit card numbers,
and set the system up to launch attacks on other systems or websites. As a
result, firewall protection from these attacks is increasingly required on
computers. Recognizing this need, Microsoft provides an integrated firewall
in Windows XP to provide immediate protection from outside access
attempts. When enabled, the Internet Connection Firewall provides basic
protection suitable for most home and small office users.
NOTE: Enabling the Internet Connection Firewall does not reduce the need
for virus-checking software.
The firewall is automatically enabled when you run the Network Setup
Wizard. When the firewall is enabled for a network connection, its icon
appears with a red background in the Network Connections portion of the
Control Panel. The Internet Connection Firewall can be applied to each
Internet connection on the computer. The firewall also provides basic
logging capabilities. Not all events that appear in the log are hacker attacks.
Many different types of harmless events can appear in the log, such as
routine checks by an Internet Service Provider to verify the presence of your
computer (pings).
18
M i c r o s o f t ® W i n d o w s ® X P Fe a t u r e s
The firewall is configured using the Properties dialog box associated with
each Internet connection in the Control Panel. The firewall can be enabled
or disabled. Additional configuration options are available for more
advanced users. These advanced options include the ability to open or close
specific Transmission Control Protocol (TCP) or User Datagram Protocol
(UDP) ports or to enable port redirection. Port redirection allows access
requests to a specific port on the firewall (such as port 80, the Web server
port) to be automatically redirected to another computer on the local
network. This capability allows a Web server on a home network to be
protected by an edge firewall.

is turned off but connected to a power source. Remote Wake Up, typically
used to conserve power in large network organizations and to remotely
perform maintenance/configuration operations, must be supported by an
ACPI-compatible computer. Additionally, to start by a network connection,
the network adapter must support WOL. To start by a telephone connection,
the modem must support WOR.
RIMM

has its pins lined up in even rows.
SPX
Sequenced packet exchange. A transport layer protocol that works with IPX to
ensure reliable data transmissions. See also IPX/SPX.
SRAM
Static random-access memory (RAM). Referred to as “static” because it retains
a value as long as power is supplied, unlike DRAM, which must be refreshed
regularly.
Stepping
A term used to indicate a manufacturing “version number” or “revision level”
of an Intel microprocessor. The initial version of a new processor is the A0
step. As revisions are made for functional fixes or manufacturing
improvements, the stepping is increased. Intel recommends using identical
steppings of processors in dual-processor systems.
STP
Shielded twisted pair. A common type of copper wiring used for Ethernet
networks. STP wiring is constructed just like UTP, having two insulated
copper wires wound around each other to form a “twisted pair.” However, for
some business locations, twisted pairs are also enclosed in a shield that
functions as a ground.
Subminiature-D
D-shaped connectors on your computer that typically have 9, 15, or 25 pins
and can be male or female. Also referred to as D-Sub connectors.
System Setup
A utility that allows you to configure user-selectable options in the BIOS such
as date and time, or system password, as well as to set the current configuration
information, including the amount of memory or type of hard drive installed.

Windows program applications to operate with a wide variety of telephony
devices, including voice, data, fax, video, and so on.
TCP/IP
Transmission Control Protocol (TCP)/Internet Protocol (IP). The basic
communication protocol of the Internet. It can also be used in a private
network. TCP/IP is a two-layer system. The higher layer, TCP, manages the
assembling of a file into smaller packets that are transmitted by one computer
over the Internet and received by the TCP layer on another computer. The
receiving computer’s TCP layer reassembles the packets into the original
message. The lower layer, IP, addresses each packet so that it gets to the right
destination. See IP and IP Address.
Token Ring
A network communications protocol. See also Network Adapter.
TSR
Terminate-and-stay-resident. A program application that is loaded, stays in
RAM after it is terminated, and can be reactivated by pressing a designated
“hotkey” or a combination of keys. Examples of TSRs are calculators and
calendars. OSs like Windows have the ability to constantly switch back and
forth between applications and thereby do not require TSRs.
UDMA
Ultra DMA. A hard drive protocol that allows the computer to take advantage
of fast Ultra ATA drives.
UL
Underwriters Laboratories, Inc. U.S. Federal law mandates that all equipment
used in a place of business be certified as safe by a nationally recognized test
laboratory. In addition, many local electrical and building codes and
ordinances require that products be certified by a nationally recognized test
laboratory. Because UL is one of the most widely recognized test laboratories
in the United States, many customers of large manufacturers make UL
approval a mandatory requirement.
UPS
Uninterruptible power supply. A device that allows your computer to keep
running for a limited amount of time after the primary power source is lost.
Typically, a UPS can also provide protection against power surges.

scanners, speakers, or printers, that provides a maximum transfer speed of
12 Mb/second. Devices plug directly into a four-pin connector on your
computer or into a multiport hub that connects to your computer. USB is
hot-swappable, and up to 127 devices can be connected in daisy-chain
manner.
UTP
Unshielded twisted pair. A common type of copper wiring used for telephone
systems and Ethernet networks. To reduce electromagnetic induction
between pairs of wires, sometimes called “crosstalk,” two insulated copper
wires are wound around each other to form a “twisted pair.” See also STP.

Internet standard technologies developed to unify the management of
computing environments. The core set of WBEM standards, developed by
DMTF, include a data model, the CIM standard, a coding specification, and
an http transport mechanism.
WfM
Wired for management. A specification developed by Intel to improve the
manageability of desktop, mobile, and server computers. WfM defines
software, hardware, and other capabilities that enhance computer network
operations and reduce support costs by allowing remote management
application programs to access client computers over a network. WfM
technology is used in a client computer, in such components as circuitry,
power supply, network adapter, and so on. Remote management application
programs can use WfM technology to access a client computer and gather
information about it, monitor its status, or change its operational state. WfM
standards include DMI, PXE, and Remote Wake Up. WfM is also compatible
with current and emerging industry specifications, such as ACPI, CIM,
SMBIOS, SNMP, and WBEM.
